How to determine work function
WebFundamentally, the work function can be calculated by the density-functional theory (DFT) method, on the basis of electrostatic potential across the material-vacuum interface. WebA function, by definition, can only have one output value for any input value. So this is one of the few times your Dad may be incorrect. A circle can be defined by an equation, but the equation is not a function. But a circle can be graphed by two functions on the same graph. y=√ (r²-x²) and y=-√ (r²-x²)
